Description
The application is divisional application, the application number of parent application: 201380029874.3, the applying date: and 2013.6.18,
Denomination of invention is same as the present application.
Technical field
The present invention is about a kind of polarization plates and organic EL panel.
Background technique
In recent years, popularizing with thin display, proposes there is the display for carrying organic EL panel.Known organic face EL
Plate has reflexive higher metal layer, therefore is easy to produce external light reflection or the problems such as mirroring of background.Therefore it is known that it is logical
It crosses and circularly polarizing plate is set to depending on recognizing side (depending on recognizing side) and prevents these problems.As common circularly polarizing plate, it is known to will be with
Cycloolefin (COP) resin film be representative phase difference film (representative is the plate of λ/4) with its slow phase axis relative to polarizing film
Mode be laminated person of the absorption axiss as about 45 ° of angle.There is the phase difference film of known COP system resin phase difference value not take
Certainly approximately fixed in the wavelength of measurement light is so-called gentle wavelength dispersion characteristics.In will include it is such have gentle wave
When the circularly polarizing plate of the phase difference film of long dispersing characteristic is used for the situation of organic EL panel, excellent reflection form and aspect can not be obtained by having
The problem of.
It is as described above in order to solve the problems, such as, and propose have comprising increasing i.e. with phase difference value with the wavelength of measurement light
The circularly polarizing plate (such as patent document 1) of the phase difference film of the wavelength dependence (inverse dispersion wavelength characteristic) of so-called inverse dispersion.
When such circularly polarizing plate to be used for the situation of organic EL panel, external light reflection and reflection form and aspect on positive direction are able to greatly
Amplitude improves.But when from the situation of oblique observation panel, obtain the form and aspect different from the form and aspect of positive direction, the form and aspect
Difference can become larger problem.In addition, the problem of changing with also confirming the display characteristic time dependent of panel.
